Scarlets aim to extend their winning run in the capital when they take on United Rugby Championship play-off hopefuls Cardiff at the Arms Park.

Cardiff braced for three festive derbies against Scarlets, Dragons and Ospreys that could shape their United Rugby Championship play-off hopes.

Chelsea’s substitutes have made the difference as wingers Alejandro Garnacho and Pedro Neto scored second-half goals to secure a 3-1 win at third-tier Cardiff City and a place in the English League Cup semifinals.

Alejandro Garnacho scored twice as Chelsea reached the semifinals of the Carabao Cup with a 3-1 victory at Cardiff City. Substitutes Garnacho and Pedro Neto struck second-half goals as Chelsea unleashed the power of their bench against their Welsh hosts.

Chelsea boss Enzo Maresca has changed his entire team from the 2-0 Premier League win over Everton on Saturday. Cole Palmer is rested and Marc Cucurella is suspended but there's no shortage of quality and experience in this line-up. Moises Caicedo returns to captain the team, while there are starts for the likes of Marc Guiu and Facundo Buonanotte.

Yet even with the lead, Chelsea still allowed Cardiff to get back in the game, conceding an equaliser in the 75th minute. Had it not been for Pedro Neto’s late winner, the Blues were looking at a shock scoreline once the final whistle sounded.
